Applications of BCI systems comprise the restoration of movements, communication and environmental control. In this study experiments were made that used the BCI system to control or to navigate in virtual environments (VE) just by thoughts. BCI experiments for navigation in VR were conducted so far with synchronous BCI and asynchronous BCI systems. The synchronous BCI analyzes the EEG patterns in a predefined time window and has 2 to 3 degrees of freedom.1 p.application/pdfeng(c) Mary Ann Liebert, Inc., 2009Realitat virtualPercepcióCervellVirtual realityPerceptionBraininfo:eu-repo/semantics/article6170072015-05-12info:eu-repo/semantics/openAccess
